Key Features
Coherent Optics Technology
Coherent optics on the line side. Managed wavelengths at 1G / 10G / 100G / 400G. 800G is available today as Optical Spectrum, after we measure the line parameters on your route.
Deterministic Latency
Optical-layer transport adds zero processing delay beyond speed-of-light propagation. Critical for financial trading, real-time replication, and HPC workloads.
Protocol Transparent
Carry any protocol — Ethernet, Fibre Channel, OTN, SDH — natively at the optical layer. No encapsulation overhead, no MTU limitations.
1+1 Optical Protection
Optional dedicated protection path. Both working and protect paths are provisioned and monitored.
Your Own Spectrum
Bring your own transponders and run them on dedicated 112.5 or 150 GHz spectrum on our DWDM line system. See Optical Spectrum.
OAM & Performance Monitoring
Real-time optical performance monitoring including OSNR, pre/post-FEC BER, chromatic dispersion, and PMD. Alerts before degradation impacts service.
Use Cases
Financial Services
Ultra-low-latency optical paths for algorithmic trading, market data distribution, and real-time risk computation between trading venues.
Inter-DC Backbone
High-capacity optical links between data centers for storage replication, backup, and disaster recovery with guaranteed bandwidth and zero jitter.
Carrier Backbone
Wholesale wavelength services for carriers building long-haul networks across Southeast Europe without investing in their own DWDM infrastructure.
Available in these cities
Service delivery across all 18 Sofia Connect PoPs.
